We started racing rotaries because we could not afford two or three race engines per season with piston engines.
Poorly thought out support systems or incorrectly assembled engines are the only ways I know of to stop a rotary engine. They used them in pumping stations up North where they only looked in on them every six months. Can you imagine a piston engine under load for six months? Keep it cool. Keep it lubricated and keep it under 10,000 RPM (13,000 RPM) with lightened rotors and more mods for clearance and it will be very reliable.
